Bis(μ-4-methylbenzoato)-κ³ O,O′: O;κ³ O:O,O′-bis[aqua(4-methylbenzoato-κ² O,O′)(nicotinamide-κN ¹)cadmium]

In the dinuclear centrosymmetric title compound, [Cd2(C8H7O2)4(C6H6N2O) 2(H₂O)2], the Cd^II ion is chelated by two carboxylate groups from 4-methylbenzoate anions, and is further coordinated by one nicotinamide and one water molecule; a carboxylate O atom from an adjacent 4-methylbenzoate anion bridges to the Cd^II ion, completing the irregular coordination sphere of the seven ligand atoms. In the crystal, intermolecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds link the molecules into a three-dimensional network. The methylbenzene moiety of one bridging 4-methylbenzoate anion is disordered over two orientations of equal occupancy.
